* speedup for animating bones, in one scene with sintel and a dragon animated its over 4x faster.

* utility function BLI_findstring to avoid listbase lookup loops everywhere.
  eg: 
    ListBase *lb= objects= &CTX_data_main(C)->object;
    Object *ob= BLI_findstring(lb, name, offsetof(ID, name) + 2);

* made some more math functions use const's, (fix warnings I made in previous commits)
